Nearly ideal towing machines for antique gliders are Touring Motor Gliders
as Falks, Dimonas and similar. They are able to fly slow, makes less noise
and uses less fuel.

Has any one heard of using a Champs, Cubs, Luscombs or Cessna 120/140
for tow operations for antique gliders like a franklin. I am in search
of a tow plane that can fly at 50 miles per hour or less.
